Question about Maytag 22.6 cu. ft. Side-By-Side Refrigerator with PuriClean II Ice and Water
1 Answer
The light on the outside door (where the ice/water dispenser is) won't turn off. It is dimmer than when you hit the 'light' button, but it stays on constantly when the door is shut. The 'light' button works and turns the bulb brighter, but when you turn it off, it just dims and doesn't go out. The light shuts off when the door is open and turns back on when its closed. Model Number MSD2456GEB

Hi
Reprogramming your refrigerator to only light up when the dispenser is in use saves energy and keepsyour house darker at night. The light is controlled using the buttons above the water dispenser mechanism.Press and hold the "Lock" or "Lock Controls" button for three seconds to activate the controls if they currently are locked.Tap the "Light" button to switch off the light.Press and hold the "Lock" button for another three seconds to lock the controls from further changes. The light now only comes on when the dispenser is active.
If the above procedure won't work then this will be the cause of a faulty switch. This light switch is an integrated part of the dispenser control circuit board. This will require you, or your service tech to replace the entire dispenser/ice maker control board. It will be located just behind the dispenser fascia, mounted on a bracket. the actual light switch circuit is mounted on this board.
Try this procedure:-
Shutdown the unit for five minutes. Simply unplug the unit for this length of time. This will reset the board, and possibly, fix this fault if it is not to severe. If the shutdown dose not correct the switch action, simply replace the dispenser/switch control circuit board.
Please get back to us if you have further query or else please accept the solution.

Is the sump tray full of water? or is it not filling up fast enough? Water level sensor lets control board it needs water or its full of water. If machine is not getting enough water or slow filling then check the water filter, if water is flowing good through filter good then pull water line off of the water inlet valve to make sure there is no trash blocking water at inlet. If not then make sure the water solenoid is getting power call from board to solenoid, if getting 115v to coil and slow to no water to sump then replace valve, if no power to valve then replace board.

This could be several things. This means it has tried to harvest the ice 3 consecutive times before the machine has locked out.
1. Likely Cause, Ice bridge thickness too small, not enough ice to open curtain. PROBABLE SOLUTION, Check and adjust if needed.
2. LIKELY CAUSE, ice bridge too large, ice frozen to evaporator frame. PROBABLE SOLUTION, Check and adjust if needed.
3. LIKELY CAUSE, Purge valve does not open, water melts ice bridge, not enough ice to open curtain. PROBABLE SOLUTION, Check purge valve during harvest.
4. LIKELY CAUSE, incomplete ice formation. PROBABLE SOLUTION, Check water distributor for partially plugged holes. The machine needs to be cleaned and sanitized every 6 months.
5. LIKELY CAUSE, Curtain out of position. PROBABLE SOLUTION, check curtain for swing restriction.
6. LIKELY CAUSE, Curtain switch dose not open when curtain does. PROBABLE SOLUTION, Check switch with ohmmeter if bad replace.
7. LIKELY CAUSE. Machine in very cold ambient. PROBABLE SOLUTION. Move machine to a warmer location.
8. LIKELY CAUSE. Hot gas valve does not open during harvest. PROBABLE SOLUTION. Check hot gas valve with a volt meter during harvest mode to see if you are getting correct voltage to it. If not then replace control board . IF yes and valve is not opening then replace valve.
9. LIKELY CAUSE. Harvest assist probe out of position - ejector pin not retracted. PROBABLE SOLUTION. Check harvest assist mechanism - spring should retract pin.
10. LIKELY CAUSE. Damaged evaporator. PROBABLE SOLUTION. Check evaporator surface. Make sure the plates where they intercept each other is not loose this will cause ice to hang up. check to make sure the nickel is not peeling off, if so then the plate will need to be replaced.
11. LIKELY CAUSE. Fan motor stays on during harvest. PROBABLE SOLUTION. Check controller using test mode. If this dose not help you then give me the model number so i know what machine you have.

This light is a harvest limit light. This light's primary function is to be on as water contacts the ice thickness probe during the freeze cycle, and remain on throughout the entire harvest cycle. The light will flicker as water splashes on the probe. The lights secondary function is to continuously flash when the ice machine is shut off on a safety limit, and to indicate which safety limit shut off the ice machine. Start up of machine after turned off. !. Before the ice machine starts, The water pump and water dump solenoid are energized for 45 seconds to purge old water from the water trough. This ensures that the ice making cycle starts with fresh water. The water fill valve energizes after 45 second water purge, and remains on until the water level probe is satisfied. 2. to pre-chill the evaporator, there is no water for the first 30 seconds of the freeze cycle. 3. The water pump starts after 30 seconds pre-chill. An even flow of water is directed across the evaporator and into each cube cell.

There can be a few reasons why your Scotsman DCE33PA1SC ice machine is not making ice, even though it has power and water:

1. Thermostat: The thermostat controls the temperature inside the machine. Make sure that the thermostat is set to the proper temperature and that it is functioning properly.
2. Water inlet valve: The water inlet valve is responsible for letting water into the ice maker. Make sure that it is functioning properly and that it is not clogged with debris.
3. Water pump: The water pump is responsible for circulating water through the ice maker. Make sure that the pump is functioning properly and that it is not clogged with debris.
4. Water filter: Make sure that the water filter is clean and not clogged.
5. Control board: The control board controls the operation of the ice maker. Make sure that the control board is properly connected to the power source and that it is not damaged. It's possible that the control board is malfunctioning, which can cause the ice maker to not work correctly.
6. Refrigerant levels: low refrigerant levels can cause the evaporator to freeze over, which can affect the ice production. Make sure the refrigerant level is adequate.

It's best to consult the user manual or to contact a professional technician to diagnose the problem, as the issue could be caused by a number of things and it's important to troubleshoot it correctly

Change the dual water control valve if not getting water during cycles.

Sea Breeze

does it have a float mechanism that senses the water level by any chance

you need to replace the water valve

First make sure that the cleaning valve is closed, this is the White wing nut looking handle on the side wall under the inlet water valve. This handle has to be in the closed position which is horizontal to the base it closes a micro-switch. If the handle is loose turn the power switch to Ice have the handle in the open position and feel with your finger behind where the handle closes and push the micro-switch in manually and hold for a few seconds and see if the Power OK light comes on on the control board in the control box.

There's an ice- or water-dispensing problem The ice and water-dispensing system of your refrigerator is quite complex. Many components work together to provide the ice and water. Aside from a simple problem of a leaky water tube or a jammed ice chute, most other components are not user serviceable. We suggest that you contact a qualified appliance repair technician for such repairs.
